I'd have to listen to the podcast again, but I think Robb mentioned that the less pure of a fish oil you get there's some possibility of GI issues (interestingly enough though he said you can't get mercury poisening from fish oil - didn't know that) and other issues that might arise... Personally, I think the Costco enteric brand might not be super-terrible if someone absolutely didn't want to drink it as a straight liquid. I'm going to try drinking it as a straight liquid and I don't even know if I'll be able to handle it. It may end up in my dog's food dish just like when I tried Greens+ haha.
